[linux-lvm] problem with vgcreate

[Robert L. Harris]

I'm trying to create a LVM for a system.  I partitioned my drives,
rebooted and do my pvcreates but then it blows up on vgcreate.  The
drives are both 18Gig, I've duplicated the partitions so they're
identicle size even though they're going to be concats, not stripes.

Here's a screen dump just made a bit readable.

root at performance:/root# pvcreate /dev/sda2
pvcreate -- physical volume "/dev/sda2" successfully created

root at performance:/root# pvcreate /dev/sdb2
pvcreate -- physical volume "/dev/sda2" successfully created

root at performance:/root# pvscan -v
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- walking through all physical volumes found
pvscan -- no valid physical volumes found

performanc:/root# vgcreate -v lvm-vg1 /dev/scsi/host0/bus0/target0/lun0/part2 /dev/scsi/host0/bus0/target1/lun0/part2
vgcreate -- checking volume group name
vgcreate -- checking volume group directory existence
vgcreate -- locking logical volume manager
vgcreate -- checking volume group "lvm-vg1" existence
vgcreate -- counting all existing volume groups
vgcreate -- reading all physical volume data from disks
vgcreate -- checking if all given physical volumes in command line are new
vgcreate -- no valid physical volumes in command line

root at performance:/root# vgcreate -v lvm-vg1 /dev/scsi/host0/bus0/target0/lun0/part2 
vgcreate -- checking volume group name
vgcreate -- checking volume group directory existence
vgcreate -- locking logical volume manager
vgcreate -- checking volume group "lvm-vg1" existence
vgcreate -- counting all existing volume groups
vgcreate -- reading all physical volume data from disks

Just to verify my devices, etc
